Summary
Chirality in coordination chemistry, though known since 1920, was neglected until recent advances. This study demonstrates how ligand choice and metal center configuration can predetermine the chirality of coordination compounds, including helicates.
Area of Science:
- Coordination Chemistry
- Asymmetric Synthesis
- Chirality Studies
Background:
- Asymmetric synthesis in coordination chemistry was established in 1920 but largely overlooked for decades.
- Recent advancements in polynuclear systems, supramolecular structures, and enantioselective catalysis have revived interest in chiral coordination chemistry.
- The stereoview of [Ru(bpy)3]2+ highlights the importance of chirality in modern chemical research.
Purpose of the Study:
- To explore the predetermined chirality in coordination chemistry.
- To showcase examples of controlling chirality through ligand selection and metal center configuration.
- To bridge the gap between historical knowledge and current applications of chirality in coordination compounds.
Main Methods:
- Ligand selection strategies for inducing chirality.
- Metal center configuration analysis in chiral complexes.
- Helicate structure analysis for predetermined chirality.
Main Results:
- Demonstration of predetermined chirality in various coordination systems.
- Identification of key factors (ligand, metal center) influencing chirality.
- Examples illustrating the control over enantioselectivity in coordination compounds.
Conclusions:
- Ligand choice and metal center configuration are crucial for predetermining chirality in coordination chemistry.
- The principles discussed are applicable to polynuclear systems, supramolecular structures, and enantioselective catalysis.
- This work revitalizes the study of asymmetric synthesis in coordination chemistry.

Molecules with Multiple Chiral Centers
15.2K
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

Chirality
29.7K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Chirality in Nature

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Metallic Solids
20.9K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

Lattice Centering and Coordination Number
12.0K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
